Description
Technical field
The present invention relates to a kind of water test unit, particularly a kind of steel cylinder water test unit.
Background technology
As a kind of pressure vessel that security performance is had relatively high expectations, the test of hand fire extinguisher steel cylinder or similar containers comprises the hydraulic testing.The fundamental purpose of the hydraulic testing is to check that bottle and weld seam have or not leakage and bottle to have or not distortion.
Now people mainly are to rely on manually-operated when carrying out the hydraulic testing, can not realize steel cylinder carried out operations such as automatic voltage measurement, warning.This method not only labour intensity is big, inefficiency, and also it is big to operate the test findings error that causes easily lack of standardization, is unfavorable for that simultaneously large-scale production detects.
Summary of the invention
Technical matters to be solved by this invention is the deficiency to prior art, provides a kind of easy to use, can carry out the steel cylinder water test unit of automatic voltage measurement to steel cylinder.
Technical matters to be solved by this invention is to realize through following technical scheme.The present invention is a kind of steel cylinder water test unit; Be characterized in: comprise pressure testing water tank, test pipeline and return pipe; Be provided with test pump, retaining valve, electrohydraulic pressure control table and accumulator successively on the water inlet end of test pipeline; Also be connected in series on the test pipeline and be provided with several pressure testers, described pressure tester comprises solenoid valve and pressure testing pipe, and solenoid valve also is connected with test pipeline, return pipe and pressure testing pipe respectively; The pressure testing pipe is provided with the pressure testing pipe adapter that matches with the steel cylinder bottle neck, also is connected with test gauge on the described pressure testing pipe; It also is provided with the standard testing pipeline, and the standard testing pipeline is provided with master gauge, and the standard testing pipeline also is connected with test gauge and on its connecting line, is provided with stop valve, and described water inlet end feeds the pressure testing water tank.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described steel cylinder water test unit is characterized in: the backwater end of described return pipe feeds the pressure testing water tank.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described steel cylinder water test unit is characterized in: it also is provided with water-storing tank, is provided with electric heater in the water-storing tank.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described steel cylinder water test unit is characterized in: on the pipeline that connects test pipeline and pressure tester, be provided with relay, relay is connected with alarm.
Compared with prior art; The present invention extracts water in the pressure testing water tank out through accumulator and solenoid valve through test pump and pressurizes back pressurize 1 minute, viewing test tensimeter for steel cylinder to be tested; After accomplishing, pressure testing, simultaneously water is emitted through return pipe through the solenoid valve pressure release.It once can carry out pressure testing for simultaneously 4-10 steel cylinder, but 3000 left and right sides steel cylinders of pressure testing every day.It is simple in structure, and is easy to use, can carry out automatic voltage measurement, warning to steel cylinder.Practice thrift the energy simultaneously, reduced working strength of workers, improved work efficiency.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Embodiment 1.With reference to Fig. 1.A kind of steel cylinder water test unit; Comprise pressure testing water tank 1, test pipeline 12 and return pipe 13; Be provided with test pump 2, retaining valve 3, electrohydraulic pressure control table 4 and accumulator 5 successively on the water inlet end of test pipeline 12; Also be connected in series on the test pipeline 12 and be provided with several pressure testers, described pressure tester comprises solenoid valve 8 and pressure testing pipe, and solenoid valve 8 also is connected with test pipeline 12, return pipe 13 and pressure testing pipe respectively; The pressure testing pipe is provided with the pressure testing pipe adapter that matches with steel cylinder 11 bottle necks, also is connected with test gauge 10 on the described pressure testing pipe; It also is provided with the standard testing pipeline, and the standard testing pipeline is provided with master gauge 7, and the standard testing pipeline also is connected with test gauge 10 and on its connecting line, is provided with stop valve 6, and described water inlet end feeds pressure testing water tank 1.
Embodiment 2.In embodiment 1 described steel cylinder 11 water test units: the backwater end of described return pipe 13 feeds pressure testing water tank 1.Water in the pressure testing water tank 1 just can recycle like this.
Embodiment 3.In embodiment 1 described steel cylinder 11 water test units: it also is provided with water-storing tank, is provided with electric heater in the water-storing tank.Under the lower situation of water temperature, the water in the heating water-storing tank makes and reaches the required temperature of test like this.
Embodiment 4.In embodiment 1 described steel cylinder 11 water test units: on the pipeline that connects test pipeline 12 and pressure tester, be provided with relay 9, relay 9 is connected with alarm.The electric signal that relay 9 provides according to electrohydraulic pressure control table 4 starts alarm equipment alarm.
During enforcement, earlier the water of uniform temperature in the water-storing tank is filled with hand fire extinguisher steel cylinder 11 or similar containers, after steel cylinder 11 bottle necks of fills with water are linked to each other with the pressure testing pipe adapter.To system's pressurization, prescribe a time limit when pressure is elevated to going up of electrohydraulic pressure control table 4 rated pressure simultaneously by accumulator 5 storage pressures through motor test pump 2 for energized, and electrohydraulic pressure control table 4 sends electric signal, cuts off test pump 2 power supplys; The pressure that this moment, system leaned on accumulator 5 to discharge works on.Prescribe a time limit when system's internal pressure arrives the following of electrohydraulic pressure control table 4 rated pressure, electrohydraulic pressure control table 4 sends signal, connects test pump 2 power supplys and pressurizes to system, and so circulation finishes up to pressure testing.Owing to installed accumulator 5 additional, can make energy saving of system more than 60%.
Intrasystem pressure gives steel cylinder 11 pressurizations through the solenoid valve 8 of pressure tester, viewing test tensimeter 10, and when pressure reaches 2.1MPa, pressurize 1 minute.If any leakage, electrohydraulic pressure control table 4 will be given relay 9 electric signal in the pressure maintaining period, and relay 9 will start alarm reports to the police, thereby causes pressure testing personnel's attention.If do not leak, carry out pressure release through solenoid valve 8 again, the water of pressure release flows out through return pipe 13.After finishing, pressure testing again the water in the steel cylinder 11 is put in the water-storing tank into the water in the realization water-storing tank and the recycle of heat.
For increasing work efficiency, increase reliability of testing result, it also is provided with the standard testing pipeline, and the standard testing pipeline is provided with master gauge 7.Master gauge 7 plays the check and correction effect, can proofread test gauge 10 at any time like this, has guaranteed reliability of testing result.
